Galaxy S21 (S30)'s Exynos 1000 chip could do the unthinkable10
E 1+3+4— Ice universe (@UniverseIce) September 18, 2020
The Exynos 990 that powers the European and Middle Eastern variants of the Galaxy S20 is a 7nm chip with two Mongoose cores, two Cortex-A76 middle cores, and four Cortex-A55 little cores.
The Snapdragon 865, which fuels the rest of the models, is also a 7nm SoC, and it features one prime Arm Cortex-A77 core, three high-performance Cortex-A77 cores with lower clock speeds and smaller caches, and four Cortex-A55 efficiency cores.
Perhaps the proprietary Mongoose CPU was Exynos 990's biggest undoing, and it stood no chance against the powerful Cortex-A77.
Samsung has learned a lot since and has given up on its in-house CPU ambitions.
The other three cores will probably be the new Cortex-A78 which promises a 20 percent increase in performance when compared to the Cortex-A77. Arm also says that SoCs with A78 cores will match their A77 counterparts using only half the power.
As for the remaining four cores, they will probably be the Cortex-A55.
An identical core configuration in no way guarantees similar performance, and an earlier leak has already warned us that the Exynos 1000 will lag behind the Snapdragon 875 in both performance and graphics.
The good news is that the gap will at least shorten next year, and the Exynos1000 is also expected to be more power-efficient.
Unfortunately, Samsung's next flagship silicon will probably stick with a Mali GPU, as the first AMD-made custom GPU is not expected to make a debut until 2022.
